CABLE ATTACHMENT.

, Urgnal application iled August 24, 1921, Serial No. 495,059.

Divided and this application tiled September 13, 1923. Serial No.662,404.

To all whom t may concern:

Be it known that I, JAMES F. REILLY, a citizen of the United States,residing at 4Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in CableAttachments, of which the following is a specification.

My invention relates to cable attachments, that is to say, to a device`adapted to be mounted upon a hoisting or power cable for ,the purposeof supporting the load or taking the strain thereof.

`In my previous application for Letters Fatent, filed August 24, 1921,Serial No. 495,059, of which this applicationL is a division, there isshown and described an in- `vention relating to trolleys or .travelingcarriages for elevating and transporting` the buckets used in trench andother similar engineering operations, and having as one of the featuresthereof means for positively supporting the load in the elevatedposition while the same is being transported by said trolley orcarriage.

Heretofore, in the use of hoisting and `power cables, considerablediiiiculty has been experienced in providing attachments for lsupportingthe load and taking the strain which could be adjustably mounted upon1the relatively stiffwire cables and which, when mounted at the desiredplace upon the loable, would ibe firmly Vheld against shifting1vthereon. Various constructions have been 7 "employed, such as thoseembodying'the use yofsplitvsleeves, and securing means were .usuallyemployed having projecting parts which were liable to foul on the otherparts ofthe apparatus in connection With which the` cableis used, butsuch constructions were Vmore 0r less objectionable and unreliableinuse.

The principal object, therefore, of my ,"present .invention is toprovide an attach ment adaptedto be secured upon afhoisting cable, in`apparatus of the character such, for example, as that set forth in myprevious application for Letters Patent aforesaid, for

supporting the load which is carried by they hoisting cable, but whichattachment, however, isalso adaptable for Aother purposes when mountedupon hoisting and power vcables for taking the strain therein.V Afurther object of my invention is to provide a device of the characteraforesaid, with means for .adjustably securing the attachment to thecable whereby the same will be precluded from shifting with respectthereto when subjected to the strains resulting from the intended usethereof,

The nature and characteristic features of my present invention willbevmore readily understood from the following description, taken inconnection with the accompanying drawings forming part hereof, in which:

Figure l is a vertical, central section of a trolley or carriage adaptedto travel upon an overhead trackway, with a hoisting cable shown inconnection therewith, and provided with a cable attachment embodying themain features of my present invention, said attachment being shown inside elevation;

Fig. Q is a vertical, central section, enlarged, of the cable attachmentshown in Fig. l of the drawings; `and Figg 3is a horizontal sectionthereof, taken approximately on the line 3-3 of Fig. 2. Referring nowmore particularly to Fig. l of the drawings, there is there shown a`trolley or `carriage embodying one type of apparatus in connection withwhich my present invention is adaptable for use. A detailed descriptionof the construction, arrangement and operation of said trolley orcarriage is fully set forth in my previous application for LettersPatent, Yhereinbefore referred to, the same comprising a suitableframework 4-0, preferably built up of structural shapes and plates, andprovided at the upper corners thereof with means for supporting studshafts 4t2, for journaling the wheels 43 which are adapted to run upon'the upper surfaces of the lower iianges of an l.lf-beam 13, said I beamforming a trackway uponwhich said trolley is adapted to travel. Theframework 40 also carries means for supporting a shaft 45, upon whichshaft a sheave ,46 is mounted, and over which sheave passes the hoistingcable 27 for elevating the buckets or other load, which may bel securedupon the" lower end of said cable 27 in any suitable manner.A

Journaled in eachlof lthe lower corners of the framework 40 is atransversely, arranged shaft 50, each of which shafts has securedthereto a dog or latch 51, A The dogs or latches 51 normally rest upon abar 52secured to ythe framework .at each side,.soasto form positivemeans of support for the latches 51 when the load comes thereon,- as ismore fully explained in my previous application hereinbefore referredto. The upper inner ends of the latches '-51 may be recessed, as at 53,complementa] tothe .shape lof :the -cable attachment 28, which comprisesthe essential novel `feature of my present invention. It Will, ofcourse, be understood vthat .the particular manner ofoperation, asWellas the specific construction', of the ltrolley or carriage abovedescribed formsno essential part of the presentinvention, vbut Ithelsame is illustrated inconneetion-vvith the cable attachment 28 toshovvmoreparticularly one Way in Which theusame ,is kadapted to .beused. v

l The cable attachment 28, in the particular embodiment of my inventionshown in the drawings, comprises `a member preferably spherical inlshape and adapted to be vadjustably .but firmly clamped upon thefcable. *F or .the purpose of clamping the attachment 28.at the properlocation on the cable-27, the attachment 28 is provided with .a.verticalcentral hole or bore 29, through Which'the cable 27 extends,and there are also provi-ded interior recesses 30, off-set lon eachsideof the central bore 29 (see Fig. f The cable 27 vis engaged at each ofthe olf-set recesses-30 by a lU-bolt-31, provided ivithnuts 32 threadedon its ends andseat- .fed ,in -recesses 83, whereby the ends of the{Ll-'bolts u31,.and the nuts 32 which are mountfedfthereon, Will notproject beyond the outer .'spherical sur-face of the attachment 28. The`v`arrangement is such that, as the nuts 32 ,are advancedon vthethreaded ends of the U-boltsi'31, the cable vWill be deformed from lvastraight lineand lsufficiently drawn Withi in {thehrecesses 30 to clampthe member 28 upon--thecable 27 .at any desired location.

HFor' the purpose of reinforcing the U- `bolts 31, `therefis provided,oppositeeach of lsaid bolts, a block 33, slidably mounted inalcomplementally shaped openingand held in position by means of a plug.34 which is threaded'in the member 28 and bears against the other end.ofthegblock 33.

the foregoing arrangement, there Will be'provided anattachment forcables which maybe .mounted thereon at any desired posiyftion, .which,attachment is particularly y,adaptableforsupporting the load or talringthe strain-in yconnection with `Wire and .,s-imilarstiff cables and-thelike, Whichhvh'en n `lso mounted upon the cable, will be securely andlfirmly vheld against shifting thereon, .which is so constructed andarranged that the stresses Withinthestructure Will be Well taken care-of,and Which-is also characterized by lthe absencev of projecting partsWhich Would interfere vvith the'coaction of the attachment with theother parts of the apparatus `in connection with which the sameis used,and which is further characterized by the integral formation of the mainbody portion of the attacluncnt.
